Scientists have finally hit Greenland's bedrock last week. And now they say the buried rock holds secrets to how Earth's climate changed 100,000 years ago. And what this has on the implications of today's climate upheaval.

Scientists collected ice cores, cystallized ice that contains air bubbles from previous time periods dating back to the Eemian Period, around 10,000 to 115,000 years ago. They want to analyze the sames to help us understand the impacts of global warming. According to project head Dorthe Dahl-Jensen of the university of Copenhagen:
"Our findings will increase our knowledge on the climate system and increase our ability to predict the speed and final height of sea level rise. If the Eemian was unstable, then the models of future change due to increased greenhouse effect are wrong as they cannot handle sudden changes."
